I use this product with the optional RX Lens Insert. The eyeshield safety glasses kit is well constructed and priced right. I don't have any complaints with it. My only problem is with the RX Insert, which is not adjustable. I use no line bifocals, and I have a problem lining up the insert for clear vision. Because the insert cannot be bent or adjusted, I have difficulty finding the correct viewing "spot."

Purchased to use in the operating room and they seem to provide great coverage. I am eager to get the prescription inserts now as I think that really rounds out the product.

I found the system to be absolutly spot on for the type of work. I wore my set every day in afghan for six months. The only problem now back in UK is the nose piece is knackered.

I purchased these glasses to use for shooting.I also added the RX Insert Option and had my prescription added by my Optician. These are sturdy, comfortable glasses and I like the option of having interchangable lens although the green gets the most use for me. The design offers good protection for the eye and good visibility. I think these are great glasses considering what some other name brands cost.
